high voltage network monitoring
Licenced network operators do experience faults on their electricity distribution networks, which result in Customer Interruptions (CIs) and Customer Minutes Lost (CMLs). Most CIs and CMLs are incurred on the high voltage network. Operators implement a number of measures to reduce the amount of CIs and CMLs incurred like remote control and automation. Prior to these technology advances, responding to 11kV network faults relied on operatives attending site to manually switch the network in distribution substations. This took time and increased the duration of CIs.
